Mend Caroma Uniset Toilet Cistern Overflow

caroma uniset overflow?

Hi,
I have a drip through the internal overflow in a caroma uniset toilet cistern. I have replaced the ball cock washer but it never quiet turns the valve off. It will turn off if I lift the float arm WELL above where it would normally stop but I cant get the bugger to turn completely off when the float reaches its highest point.

Any suggestions would be appreciated.

Caroma Caroma Uniset D.I.Y, Toilets Toilet Cistern Overflow

Requires small soldering iron.

I found a band aid solution.
Go back to where you have removed the washers.
There is a small inlet hole beneath the black washer.
It is in the shape of a small volcano (ie cone).
There will be a tiny crack (2 to 3 mm).
You may have to use a magnifying glass but the crack will be discolored.
Next is tricky. Skillfully melt the plastic and fuse the crack, 'grafting' some more plastic into that area.
Smells like a burnt toothbrush.
Sandpaper off any high spots around the perimeter of the hole.
Reassemble (with fingers crossed).
I had nothing to loose. This was my last attempt and it was successful.
